Re: New IMPROVED Beta 5

This is the issue, those regultions require amounts of light which look totally redundant to me. People write such regulations (also concerning CRI requirements for street lighting, not only brightness) because they are spoiled, just like kid with lots of money in a toys shop. Few decades ago street...

Re: New IMPROVED Beta 5

Usually the point of all thos replacements is to replace the lantern too (big time waste if you ask me - The old lanterns are reliable and working, and im not buying that the replacements are done to save energy as claimed, since in none of the cases the new lamp is lower wattage than the old - at l...

Re: New IMPROVED Beta 5

I can agree with that.... Also does it require a mod ? 18w SOX can run on 18wT8 ballast, so i'd assume the opposite too. Now, IIRC there was some halide that worked ok on the 18wT8 ballast too. If thats right, does it mean that such halide can work straight on the 18w SOX gear with only a socket ada...

Re: GU10 fluorescent downlighters

For LED yeah i can see why, the 12v driver is prone to less trouble than the 240v one. But the real damn thing i seen is the 240v 2-pin (not GU10) halogens. 240v in a socket of the same type like 12v halogens use, in a damp environment - i dont like it much

Re: A worrying and depressing trend...

It looks so. Note that the Polish/German lamps you find might well be NOS - were stored for a while because of low demand on small suppliers, and it is possible that they indeed mocve them to China I seen this done with most Osrams stuff except only for the Lumilux which are Germany.

Re: SON UV radiation

The intense light alone can cause the eyes ti hut (maybe so,ething to do with color ?) but i dont think it makes much UV with the outer glass intact. Mercs give out more UV if judging by the yellowing of plastic covers on merc vs SON GEC lanterns

Re: Kitchen LED Replacements

Thats good figures. I'd be more concerned with the life of those LEDs. To dissipate 5w safely a heatsink with fins is required, and to haqve effect it should have air movement around it -- it does not help if it is stuck in the halogen spotlight's reflector etc

Re: Self ballasted mercury vapour help

The failure to start is indeed related to the starting probe (most likely), there can be some failure modes - broken welding on the resistor, mercury drop inside the arctube shorting the probe to the electrode (preventing it from working at all) etc. Other possibiity is contamination or wrong pressu...

Re: T8 36w Polylux Fails to Strike

That happens sometimes. Electronic starter would go well, if not then you could try putting it with stuck starter and warmig its entire length with a heat gun, then letting it start (basically can try manua l start by removing the stuck starter from the socket)
